D$7\mathrm{.}83$ A source follower is required to deliver a $0\mathrm{.}5-$V peak

sinusoid to a $2-$kQ load. If the peak amplitude of vgs is to

be limited to $50$ mV$,$ and the MOSFET transconductance

parameter kn is $5$ mA$/$V$\text{'},$ what is the lowest value of ID at

which the MOSFET can be biased? At this bias current, what

are the maximum and minimum currents that the MOSFET

will be conducting $($at the positive and negative peaks of

the output sine wave$)?$ What must the peak amplitude

of vsig be$?$
